In general, it has been found that cancer fatalism is negatively associated with important cancer prevention and control behaviors, whereas religiosity is positively associated with these behaviors. Yet, the notion that religiosity gives rise to fatalistic beliefs that may discourage health behaviors is deeply ingrained in the public health literature. In addition, racial/ethnic group membership is associated with higher reports of cancer fatalism, though this association may be confounded by socioeconomic status (SES).

The CRUZA trial tested the efficacy of an organizational-level intervention to increase capacity among Catholic parishes to implement evidence-based interventions (EBIs) for cancer control. This paper examines the external generalizability of the CRUZA study findings by comparing characteristics of parishes that agreed to participate in the intervention trial versus those that declined participation. Sixty-five Roman Catholic parishes that offered Spanish-language mass in Massachusetts were invited to complete a four-part survey assessing organization-level characteristics that, based on the Consolidated Framework for Implementation Research (CFIR), may be associated with EBI implementation.

Background: Although a quarter of Americans are estimated to have multiple chronic conditions, information on the impact of chronic disease dyads and triads on use of complementary and alternative medicine (CAM) is scarce. The purpose of this study is to: 1) estimate the prevalence and odds of CAM use among participants with hypercholesterolemia, hypertension, diabetes, and obesity; and 2) examine the effects of chronic condition dyads and triads on the use of CAM modalities, specifically manipulative and body-based methods, biological treatments, mind-body interventions, energy therapies, and alternative medical systems.

Methods: Data were obtained from the 2012 National Health Interview Survey and the Adult Alternative Medicine supplement.

Background: The Affordable Care Act (ACA) required most insurers and the Medicare program to eliminate cost sharing for screening mammography.

Methods: We conducted a difference-in-differences study of biennial screening mammography among 15,085 women 65 to 74 years of age in 24 Medicare Advantage plans that eliminated cost sharing to provide full coverage for screening mammography, as compared with 52,035 women in 48 matched control plans that had and maintained full coverage.

Results: In plans that eliminated cost sharing, adjusted rates of biennial screening mammography increased from 59.

Evidence-based interventions (EBIs) to promote cancer control among Latinos have proliferated in recent years, though adoption and implementation of these interventions by faith-based organizations (FBOs) is limited. Capacity building may be one strategy to promote implementation. In this qualitative study, 18 community key informants were interviewed to (a) understand existing capacity for health programming among Catholic parishes, (b) characterize parishes' resource gaps and capacity-building needs implementing cancer control EBIs, and (c) elucidate strategies for delivering capacity-building assistance to parishes to facilitate implementation of EBIs.

Tobacco companies in the United States are prohibited from making reduced harm claims without filing a modified risk tobacco product application with the Food and Drug Administration and obtaining an order to market as such. However, it is possible that product marketing may suggest reduced risk to individuals. This study examines perceptions, in particular those related to harm and addiction, of snus print advertisements using a combination of eye-tracking, survey, and semistructured interviews.

Background: Faith-based organizations (FBOs) have been successful in delivering health promotion programs for African Americans, though few studies have been conducted among Latinos. Even fewer have focused on organizational change, which is required to sustain community-based initiatives. We hypothesized that FBOs serving Latinos would be more likely to offer evidence-based strategies (EBS) for cancer control after receiving a capacity enhancement intervention to implement health programs, and designed the CRUZA trial to test this hypothesis.

Acculturation may influence health behaviors, yet mechanisms underlying its effect are not well understood. In this study, we describe relationships between acculturation and health behaviors among low-income housing residents, and examine whether these relationships are mediated by social and contextual factors. Residents of 20 low-income housing sites in the Boston metropolitan area completed surveys that assessed acculturative characteristics, social/contextual factors, and health behaviors.

Through two case studies of Catholic parishes in Massachusetts, this study explores the implications of leader-centered versus distributed leadership in Catholic parishes for the implementation of evidence-based health interventions. The two parishes involved in the study differ from each other in several ways. In the first, parishioners are less engaged in leadership activities at the decision-making level in the parish.

Large-scale surveys that assess cancer prevention and control behaviors are a readily available, rich resource for public health researchers. Although these data are used by a subset of researchers who are familiar with them, their potential is not fully realized by the research community for reasons including lack of awareness of the data and limited understanding of their content, methodology, and utility. Until now, no comprehensive resource existed to describe and facilitate use of these data.
